Colour temperature cannot change

[Consistos]

Using asahi-edge on a M2, on both Wayland and X11, KDE's night colours, gammastep (Wayland) and redshift (X11) does not change the colour temperature.

gammastep -v:

Notice: Temperatures: 6500K (Day), 4500K (Nuit)
Notice: Brightness: 1.00:1.00
Notice: Gamma (Day): 1.000, 1.000, 1.000
Notice: Gamma (Nuit): 1.000, 1.000, 1.000
Error: Could not control gamma, exiting.
Error: Failed to start adjustment method: wayland

redshift -v (X11, sorry it's in french):

This is not implemented yet in the DCP driver, it is not a bug.

Ok, thanks! And thanks for your awesome work on this great project! I'm using Asahi already as my daily driver and it's been a great ride so far! :)
Is there any rough expectation on when it might be implemented? Cause night color really makes life easier..

I believe this PR is related #119

[jannau]

Yes, with #119 Night Color in kwin 5.27.3 and later will work. Kwin is to my knowledge the only software which can use DRM/KMS' color transformation matrix (CTM) for the color temperature adjustments.
Gamma adjustment can be supported but requires figuring out how it works in detail.

This works now on KDE. If you want support with other compositors, please ask upstream to support CTM. Gamma table adjustment will probably be supported in the future, but there is no ETA.
